mesh/merge-gate pass: the change touches no module of the mesh's graph
mesh/repo-check pass: THE CHANGE ALTERS ITS OWN CHECK (merge-check.sh): main's version judged it; the change's judges the pull requests after it merges; it…
mesh/delivery superseded: a newer head of the same pull request
Remove the decision records and research efforts, which the knowledge base now holds whole (issue 426)
ADR 0290 rule 9: once the import is checked record by record, hq keeps no copy.
The records and efforts are removed; every link or path to them reads "ADR NNNN" or
"research NNN"; a design's decisions: lists "ADR NNNN". 02-DECISIONS keeps a pointer
README with the reading order's six topics, which the knowledge base reads through the
records module; 01-RESEARCH keeps a pointer README. The checks drop the rules that
judged records (the knowledge base holds each at propose; checks/README.md says where)
and refuse a record written here again. Playbooks 01 and 02 and the skills write and
read records with the knowledge base's verbs.

Process — overview

How work moves through HQ, and who may do what. In industry terms this is spec-driven development, with provenance: the decision is the why, the design doc is the spec, code: names the implementation, and the lab beds are the conformance tests — and unlike the common form, the chain itself is checked (ADR 0080, ADR 0081). Every other document in this folder is a playbook: trigger, who runs it, steps, outputs. Engineers and agents follow the same playbooks; agents must not act outside them.

The audiences

Audience Contract
Engineers Read and write everything. HQ is the single source of truth for mission, research, design, decisions and issue diagnosis.
Agents The same rights as engineers, exercised through these playbooks.
Anyone else This repository is public and written for them, but it is not a support channel. Nothing here identifies the mesh it describes.

The knowledge flow

idea ──► research ──► decision ──► 03-DESIGN/01-to-be ──► built (code repo)
 │            │                            │
 │            │                            └─► 03-DESIGN/00-as-is once shipped
 │            └────► abandoned (recorded, kept)
 └─(small/obvious, still a decision record)──────────► 03-DESIGN directly

research and decisions: in the knowledge base (knowledge-base.reserve, propose, ask, get, holds)

symptom ──► 04-ISSUES ──► diagnosis ──► code-repo fix and/or design amendment

how-we-build.md ──► constitution sync ──► knowledge base ──► injected into design meetings

The two design layers

03-DESIGN holds two layers that are never mixed:

Layer What it is Changes when
00-as-is/ The mesh that exists today. Describes shipped behaviour, including behaviour nobody would choose again. Something ships, or an as-is claim is found to be wrong.
01-to-be/ The mesh being built toward. Every statement traceable to a decision record in the knowledge base. A decision is taken or amended.

A to-be document that ships does not move. Its as-is counterpart is written or updated, the to-be document's frontmatter goes to implemented, and both stand — one describing what runs, the other recording what was intended. Deleting the intention loses the reasoning, which is the expensive half.

The playbooks

# Playbook Trigger
01 Research An idea worth investigating before committing to design
02 Graduation & design change Research concludes, or a design must change
03 Issues Something is wrong — often with the owner unknown
04 Build handoff A design is ready to be built
05 Constitution sync how-we-build.md changed a rule the mesh enforces
06 Writing a module Something that runs today must run on the mesh
07 Feature branches across repos Work that changes code, in one repo or several at once

The cycle is checked

The flow above is a rule, and a rule states how it is checked: 00-META/checks/cycle.py refuses a to-be design that names no decision, an in-progress/implemented design that names no owning code, two issue folders sharing a number or an issue report carrying a status key; a graduated research effort that does not say what it became is refused by the knowledge base's propose (ADR 0290). Run it with records.py, index.py and words.py before any HQ merge (sh merge-check.sh runs all four). The issue rules the check once held — located with an owner, resolved with a fix, a core issue with its replay — are refused at the write by the issue tracker's move (ADR 0275). What the checks cannot see — that code work actually started from a handoff — is held by playbooks 04 and 07: a feature branch exists because a design or an issue sent it.

Status lives in frontmatter, an issue's in the tracker

Design docs carry their status as YAML frontmatter (schema in playbook 02). Research efforts and decision records carry theirs in the knowledge base, which refuses a wrong one at propose (ADR 0290). An issue's status lives in the issue tracker, which refuses a wrong status at the write, and its report here carries only the day it was opened (playbook 03). There are no central status files and no decision ledger. Every decision is a record in the knowledge base — if it is worth recording it is worth a record, and if it is not worth a record it is not recorded. Cross-cutting views are generated on demand by the hq-status skill and never written to disk (ADR 0248); the decisions of a topic are knowledge-base.holds with that topic.
